[DNA content of the tumor cell. A new prognostic parameter in hepatocellular carcinoma?].

Hepatocellular carcinoma is a heterogeneous disease with considerable differences in malignant behaviour. Some relevant factors for prognosis are known. In this study we analysed DNA ploidy as a potential prognostic parameter. With DNA image cytometry we were able to differentiate between diploid, hypotriploid, triploid, hypertriploid, tetraploid and aneuploid tumours. The best prognosis was for patients with diploid, hypotriploid and tetraploid tumours with a median survival time of 41 months in contrast to 3 months for patients with triploid, hypertriploid or aneuploid tumours. There was a strong correlation between histomorphological parameters and the DNA content. The DNA content of tumour cells may be considerable clinical relevance in hepatocellular carcinoma regarding the decision as to whether or not to perform a resection. In patients with prognostically unfavorable parameters adjuvant oncological therapy may improve the prognosis.
